Industrial 1-1/2NPT Brass Swing Gate Check Valve

The 1-1/2 in NPT brass swing gate check valve is designed for one-way flow with automatic backflow prevention in fluid-handling piping systems. It features a brass body and brass swing disc, a PTFE gasket seal, and female NPT x female NPT connections, with a pressure rating of 200–300 PSI WOG and a temperature range up to 248°F (120°C). Installation is suitable in horizontal or vertical orientations with upward flow and uses ANSI B1.20.1 NPT threads. This valve is commonly used in pump discharge lines, HVAC hydronic loops, water treatment equipment, steam distribution, irrigation, and industrial process piping where reliable backflow prevention and low-pressure-drop flow control are needed; common replacements include Apollo 61-104 Series 1-1/2" Brass Swing Check Valve, Watts LFWCV Series 1-1/2" Brass Check Valve, and Milwaukee Valve UPBA-150 Brass Swing Check Valve.
